Flying inverted, or recovering from an orientation you've never been in before, usually costs a few real helicopters to learn by trial and error. HeliSense gives you somewhere to build that muscle memory first — on iPhone, iPad and Mac, one purchase covering all three through Universal Purchase. REAL TRANSMITTERS RC sims on mobile devices are typically built around a touchscreen. HeliSense also connects to a VBar Control Touch over Wi-Fi (WiFi Sim), or any transmitter with an ExpressLRS module (WiFi Joystick) — plus Bluetooth MFi controllers and on-screen sticks for everyone else. On Mac, that support widens further, to virtually any RC transmitter except toy-grade ones. For more information on supported controllers and transmitters, see helisense.app/controllers ORIENTATION TRAINER Six modes — Yaw Only, Roll Only, Pitch Only, Roll & Pitch, All Axes, and Single Axis (Random) — cover every orientation: tail-in, nose-in, either side-in, right way up or inverted. Isolate whichever axis needs the most work, then layer the others back in as each one becomes automatic, building genuine muscle memory along the way. Optional helper arrows nudge you the right way while a new orientation is still sinking in. Replay every set afterwards at ¼, ½ or full speed with a deviation gauge and stick traces, so you can see precisely what happened on each axis and fix it next time. FLIGHT SIMULATOR Free flight is where HeliSense really opens up. Immersive, photoreal scenes, and flight physics modeled on how a real helicopter actually flies — refined with feedback from national competition winners. Autorotation and overspeed are included, along with realistic engine and rotor sound, and configurable camera settings to frame the view exactly how you want. Start on the Beginner tuning preset and just fly. Sport and 3D presets are there when you want to push further, and underneath them you can dial in your own maximum pitch, headspeed, agility, control response and expo — none of which you need to touch to get started. Want to work on maneuvers like piro-flips without chasing the helicopter across the sky? No-collective mode holds it around a fixed point so you can focus on just that. Fly online with up to eight other pilots, in a public demo room or a private one you share by code (needs a Simulator or Pro purchase). CUSTOM BACKGROUNDS Turn a photo of your own field into a background, sun position included, for the Trainer and No-collective mode (needs a Trainer or Simulator purchase). IN THE BOX Two 700-size helicopters included, one electric and one nitro. More helicopters and scenery are planned as in-app purchases in future updates — some may be free. SILHOUETTE RECOGNITION A helicopter's silhouette flashes up and you pick the correctly-oriented one — quick, fun practice for reading orientation at a glance. Unlocks with either purchase. Every feature is free to try in short sessions, with no limit on how long you can keep using the free tier — just a cap per sitting. A one-time purchase (no subscription) unlocks unlimited use, and Universal Purchase means one purchase covers iPhone, iPad and Mac together. Requires iOS 26 or iPadOS 26.
